SPECIFICATION forming part of Letters Patent No. 320,703, dated June 23, 1885.

Application filed April 10, 185354 (No model.)

To @ZZ whom t may concern.-

Beit known that I, PHILLIP L. SCHMITT, of Quincy, in the county of Adams and State of Illinois, have invented a new and useful Iml provement in Lubricators, and I do hereby de- Clare that the following is a full, clear, and exact description of the same.

My invention is an improvement in lubricator-cups for locomotive-engines of that class in which the oil is fed to the working parts by displacement caused by condensation of steam brought from the boiler and in which the feed is caused to drop through a steam` space in a glass tube. i 5 The invention consists of various details of construction, the obj ect of which is to simplify the apparatus and to cause it to work Inore freely and certainly, and especially to tit the cup to supply the steam-chests of a locomotive.

In the accompanying drawings, Figure l represents the cup as attached to a locomotive, being shown in 'front elevation. Fig. 2 is a front 4elevation of the cup with a portion partly in section. Fig. 3 is a side elevation of the cup with some of the parts in section. Fig. 4 is a sectional view of a modification.

In the drawings, I4 represents the oilreser- Voir which contains the lubricatngoil. It is supported on a suitable bracket, H, which' may be attached to any convenient base. On each side of the reservoir is located a sightfeed tube, a. These glass tubes are connected directly to the reservoir by connections between the sides thereof` and the caps and lower fittings of the sight-feed tubes. At the upper end caps b, provided with stems cast therewith, lead into the interior of the reservoir at its upper end. At the bottom are tittings T, connected on one sideby a solid coupling, S, with the sides of the reservoir. The other side of the lower Iittings are connected each to a pipe, a, leading to the steamchest. From the caps b on each side equalizing branch pipes D are led to a four-way connection, O. These branch pipes serve to balance the pressure in the glass pipes and to promote the feed. To this connection is attached a pipe, P, in communication with the boiler. This is provided with a valve, c, which shuts off steam both from the reser- Voir and from the equalizing pipes. 'Ihe conI nection between the pipes P and A and the pipes D is a single casting in cross form. The steam is lead to the reservoir through a pipe, A, having a condensing-coil formed by coiling the pipe back upon itself. The lower end of the coil enters the top of the reservoir and extends near to the bottom. The coil itself surmounts in compact form the reservoir 6o and forms a condensing-chamber thereon and by its side is the iillingcap H'. Regulating valves E E, are placed in the caps b, and control the flow of oil tothe steam-chests. Stopvalves G G are placed in the fittings T. 6 5

In order to regulate the supply of steam to the condensingcoil without interfering with the passage of steam in the equalizing and feed pipes, I provide a check-valve, on., in the f1tting O just above the junction of the pipes D. 7o The whole steam-supply is obtained for the reservoir and for the equalizing-pipes through the pipe l?. This furnishes the water of condensation for the displacement of the oil in the reservoir, and it also supplies steam through the reservoir and the pipes D to the upper part of the driptubes of the sightfeed tubes, thus equalizing the pressure in these tubes against the steam from the pipes u and facilitates the feed of the oil. These latter pipes u, with the single pipe P, are the only pipes connecting with. the steam-space. In Fig. 4 is shown another form of the cup in which the oil-reservoir is supported on a bracket, k, which bracket has arms 7s It. To these arms the lower fittings of the glass tubes are fixed instead of being attached to the side of the reservoir. Vhether made in this form or in the form shown in the other ligures, the lubricator is compact and is easily applied to the locomotive. The sight-feed tubes have their connections with the reservoir near the upper part of the reservoir and their lower iittings with the pipes leading to the drysteam pipes. These sight-fecd tubes are therefore filled with steam when the cup is working.

I claim as myinvention l.. A lubricator consisting of the reservoir I, a steam-supply pipe connected with a condensing-coil communicating with the reservoir, sight-feed tubes on each side of the reservoir, equalizing branch pipes D, extending ICO from the main supply-pipe P to the caps of the sight-feed tubes, and direct connections between the sight-feed tubesand the parts to be lubricated, substantially 's described.

5 2. In combination, the Oi1-reservoir of the lubricating-cup, the steam-supply pipe P and its lateral branches D7 the sight-feed tubes arranged upon each side of the reservoir con- (lensing-coil, and the regulating-valve m,

1o placed in the said pipe A above the junction of the branches D with the pipe P, all substantially as described.

3. In combination with the reservoir of a lubrieator-cup, the pipe P and its branches D, the pipe A, extending upward from the 15 juction of the pipes P and D and terminating in a coil wound downward around the said pipe A, and communicating with the reservoir at the top thereof, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
